Hello Mac users-
There’s still a little confusion when it comes to upgrading system software on an iMac, especially one that is a few years old.
The nice part about the iMac is that they are hearty machines and last a long time. In fact I still use a 27″ Mid-2010 iMac that I’m typing this blog on as we speak, and it’s still running strong!
However, right about 2009, there was a “break” in the system software that needs to have a “paid” upgrade installed before it can progress beyond the 10.5 revisions…
Macs need to be running at least (Mac) OS X Snow Leopard (10.6.8) and have at least 2 GB of RAM installed as well as at least 8 GB of available storage space to upgrade up to Yosemite.
Some of the early models from these lines — 63 different Macs, to be precise — were running Mac OS X Tiger (10.4) or Mac OS X Leopard (10.5) by default and will need to be upgraded to Mac OS X Snow Leopard (10.6.8) prior to upgrading to Yosemite if the operating system has not been upgraded already.
Although Yosemite is free, Snow Leopard is not.
If you still are using Mac OS X 10.4, 10.5 or 10.6, in particular; make sure that any software that is important to you has a compatible upgrade version available. It is highly likely that some of your software that works with Tiger, Leopard, or Snow Leopard will not work with Yosemite.
Also, some of these early models — eight different Macs — shipped with 1 GB of RAM by default and will need to have more RAM installed prior to upgrading the operating system. You’d want to to this anyway as a precaution to ensure that your system runs smoothly and you’ll find that it crashes less. Let’s take you up to 4GB of memory if you can do it.
